To all whom'it may concern:

Be it-known that ,1, CHARLES W. BELL, a resident of- Bartlesville,.in the State of 'Oklahoma havetinvented anew and useful Improvemefyttin Pumps for .Oil andLike Wells; and. 1"do hereby declare the following to bea full, clear, and exact description thereof.

My invention I relates to pumps for oil and like wells.

In the pumping of oil great difiiculty is experienced due to the wearing away of the cups, pistons, and'plungers, due to the flowing sand that rises inthe pump and remains in suspensionas long as the fluid isagitated. Just-,as soon as the pump stops this sandsettles down around the working parts of, the pump and-tends to cause them to stick. r

The object of my invention is to provide. a pump in whichthe parts are so constructed and arranged that the cups, pistons and other working parts are so protected :fromv the lodgment of sand in and about same thatthe wear on such parts, is reduced to a minimum; and furthermore to provide for the retention of the sand in a pocket or other receptacle when the pump is stopped, so that the sandcannot work down into the working parts of the pump.

To these endsmy invention comprises the novel features hereinafter set forth and claimed.

In the drawings, Figure 1 is a vertical section" of awell showing my improved pump applied thereto; 2 is an enlarged detail of .a' portion of the pump; Fig. 3 is an enlarged view of the valve for retaining the sand in the pocket above the sand; and Figs. 4 and 5 are details of the valve.

Referring to the drawings, the numeral 2 designates a perforated pipe which extends fromthe pump to the bottom of the well. The coupling 3 connects the working barrel 4 withthe pipe 2 andfsa'id' coupling forms the seat 5 for the stand-valve 6'which may be of the ordinary construction provided with the cage 7 and the ball 8. A bushing 9 is screwed to the main body of the valve 10. Valve seat 11 en ports. the ball 12. A pin 13 passing throng the body of the valve 10 forms a stop for the ball 12.

. Threadedinto the main body 10 of the vale is the (lischargeitube 14, -This tube ispr r :yided with the ordinary leather cups 15 and cup-rings 16 engaging the inner face of the the workingabarrel 4; extends up into the chamber 17 formed by upper edge of the section 4' of the workin barrel is chamfered or beveled at 19 for t e y f working-barrel 4.;{1he upper, section 4" of the tube 18 The purpose more fully hereinafter set forth..

The bushing 20 is screwed on to the working-barrel 4' and the lower end of the tube 18 is screwed into said bushing. The outer tube 21 is screwed on to'the bushing 20 and theannular space 22 is inner tube 18 and the outer tube 21. The inner tube 18 is provided with the orifices 23 which open communication between the chamber 17 and annular chamber 22. The upper end of the inner'tube 18 is connected to the threaded bushing 24 and the cylinder to said bushing. The

2?) is also connected p ston 26 moves inthe cylinder 25 and said p ston s connected at itslower end to the P1513011 rod 27, which in turn is connected .to an ordmary ball and seat valve 28 by the pin and box 29. v

A ring 30 restsupon the upper end of the bushing 24, said ring havin the o enings 31 formed therein, The valve 32 has the formed between the pins 33 with the heads -34. These pins 33 engage the openings 31 in the ring 30 and the valve 32 is adapted to be raised and lowered to admit of thexpassage of the fluid and said valve drops by gravity in position to close the openings 31 to prevent the re- 7 turn of the sand, which collects in thepocket 35 above said valve and formed bv the cylinder 25 and the (inter tube 21.

The'tubular ex nsion 36 is connected to the outer tube 22 and the pump rod 37, which is connected to the upper end of the piston 26 passes up through said extension and through the reducer 38 into {the tubing 39 which extends up to the top of the well.

parts which go gether with sand or any gritty material in sus ension' is drawn up through. the valve 7 111K discharged into theworking-barrel 4, below the bushing'Q and filling the space between said bushing and the valve 7. Upon From the annular space 22 the fluid andsand in suspension passes through the valve 32 which is lifted by thepressurc of the fluid. As the piston rises again the fluid is forced up into the tubing 39 to the top of the well, As all wells of this character pump more or less gas with the oil, the gas rises and fills the chan'iber 17 from the top thereof down to the perforations 2Z3. Accordingly, the upper end 4" of the working barrel which extends up within thechamber '17, is surroundedvby gas. By bringing'the fluid up'through the discharge tube 14: and discharging it from the top of the workingbarrel 4 and forcing it down a\ my from the working point at thetopoi' the workingbarrel, the sand has little chance to get in between the working-barrel mid-discharge tube 14L so that the cups 15 are protected from the sand. Flll'tlltll'mtil'fl, the top of the working-barrel being beveled oti to a sharp edge, the sand is deflected by'this edgeand does not have an opportunity to collect and find its way between the working-barrel to the discharge tube. The valve 32, which is 'lit'tedby the upward movement of the fluid and sand, drops back into position and prevents the return of the sand so that the sand is pocketed or held in the. pocket 35 and when the pump is stopped this sand remains in said pocket. \Vhen the pum is started again the action of the fluid lifts the sand and carries it 'on out of the pocket and through the tube t: the top ofthc wall. In this manner .lprovide for the. retention of the'sand when the pump stops in a position where it cannot find its way down lltlLOilIO working parts of the pump and cause the same to stick and increase the wear of same. l urtherniore the reciprocating parts of the pump can be drawn up through'thc cylinder 25' without having or its seat 30.
